Thanks for using just answer.
Well, it sounds like that this acute urethral pain is due to bladder neck spasms which can occur in a patient who went for hysterectomy and oophorectomy. You need to see a urologist who should start you on a anticholinergic medication which help to stop bladder neck spasms and in turn settle this sort of pain in a week time. Other possibility is of UTI which should be ruled by checking urine routine examination.
